flex加载外部swf文件[flex-swf and flash as3 swf],并且互相通讯

http://blog.csdn.net/zyjasp/archive/2008/05/16/2452175.aspx
第一步:建立加载类[CtmObjLoader],此类可以加载文件类型 [图片文件或swf文件]
package
{

import flash.display.DisplayObject;
import flash.display.Loader;
import flash.events.*;
import flash.net.URLRequest;

import mx.core.UIComponent;

public class CtmObjLoader extends UIComponent
{
  private var ProgressHandle:Function=null;
  public var loader:Loader;
  public var _bLoaded:Boolean=false;
  public var _bShow:Boolean=true;
  //@UrlRequest  加载的地址
  //@progressHandle 加载中的处理过程
  //bShow  加载后是否显示出来 
  public function CtmObjLoader(UrlRequest:String=null,progressHandle:Function=null,bShow:Boolean=true)
  {
   super();
   if(UrlRequest)LoadThis(UrlRequest,progressHandle,bShow);
  }
  public function LoadThis(UrlRequest:String,progressHandle:Function=null,bShow:Boolean=true):void{
   RemoveChild();
            loader = new Loader();
            _bShow=bShow;
            ProgressHandle=progressHandle;
            configureListeners(loader.contentLoaderInfo);
            if(_bShow)addChild(loader);//如果需要显示，则addchild
            var request:URLRequest = new URLRequest(UrlRequest);
            loader.load(request);   
  }
  public function UnLoadThis():void{
   try{
    RemoveChild();
    this.parent.removeChild(this);
   }catch(e:Error){}
   //this=null; 
  }
  public function get content():DisplayObject{
   if(!_bLoaded)return null;
   return loader.content;
  }
  public function RemoveChild():void{
            if(_bLoaded){
             try{
              DeleteListeners(loader.contentLoaderInfo);
              loader.unload();
              if(_bShow)removeChild(loader);
              loader=null;
              _bLoaded=false;
             }catch(e:Error){throw new Error('Define ObjLoader Remove Error')}
            } 
  }
        private function configureListeners(dispatcher:IEventDispatcher):void {
            dispatcher.addEventListener(Event.COMPLETE, completeHandler);
            dispatcher.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
            dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
            if(ProgressHandle!=null)dispatcher.addEventListener(ProgressEvent.PROGRESS, ProgressHandle);
                 
        }
        private function DeleteListeners(dispatcher:IEventDispatcher):void {
            if(dispatcher.hasEventListener(Event.COMPLETE))dispatcher.removeEventListener(Event.COMPLETE, completeHandler);
            if(dispatcher.hasEventListener(HTTPStatusEvent.HTTP_STATUS))dispatcher.removeEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
            if(dispatcher.hasEventListener(IOErrorEvent.IO_ERROR))dispatcher.removeEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
            if(dispatcher.hasEventListener(ProgressEvent.PROGRESS))
             if(ProgressHandle!=null)dispatcher.removeEventListener(ProgressEvent.PROGRESS, ProgressHandle);        
        }
        private function completeHandler(event:Event):void {
         this.width=loader.content.width;
         this.height=loader.content.height;
         _bLoaded=true;        
         dispatchEvent(new Event(Event.COMPLETE));
        }

        private function httpStatusHandler(event:HTTPStatusEvent):void {
         dispatchEvent(new Event(HTTPStatusEvent.HTTP_STATUS));
        }
        private function ioErrorHandler(event:IOErrorEvent):void {
   dispatchEvent(new Event(IOErrorEvent.IO_ERROR));
        }

}
}
第二步:建立加载[flash as3 swf文件]类
//此类专提供flash as3 swf文件加载,flex swf不需要,当然也可以写成一个类,我习惯这样
package
{
import flash.display.MovieClip;

public class mySwfLoader extends CtmObjLoader
{
  public function mySwfLoader(UrlRequest:String=null, progressHandle:Function=null, bShow:Boolean=true)
  {
  
   super(UrlRequest, progressHandle, bShow);
  }
  public function get movieClip():MovieClip{
   if(!_bLoaded)return null
   return content as MovieClip;
  }
 
}
}
第三步:建立flex主文件1[mainforflex.mxml]加载flex swf外部文件用
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:ns1="ManageView.*" fontSize="12">
<mx:Script>
  <![CDATA[
   import Package.mySwfLoader;
   /*
   Flex 控制加载外部的swf文件[子文件为flex版]
   */
   import mx.managers.SystemManager;
   import mx.controls.Alert;
   import Package.CtmObjLoader;
   import flash.utils.setTimeout;
   [Bindable]private var _CtmObjLoader:mySwfLoader;
   private var LoadedSM:SystemManager;
   private var loadedMoiveClip:MovieClip;
   private function LoadSwf():void{
    LoadedSM=null;
    loadedMoiveClip=null;
    if(_CtmObjLoader){
     _CtmObjLoader.LoadThis('flexchild.swf');//child.swf自己定义去吧
    }else{
   
     _CtmObjLoader=new mySwfLoader('flexchild.swf');
     _CtmObjLoader.addEventListener(IOErrorEvent.IO_ERROR,OnFailHandle);
     _CtmObjLoader.addEventListener(Event.COMPLETE,OnCompleteHandle);
     this.addChild(_CtmObjLoader);

    }
    _CtmObjLoader.setStyle('horizontalCenter',0);
    _CtmObjLoader.setStyle('verticalCenter',0);   
   }
   private function OnFailHandle(e:Event):void{
    mx.controls.Alert.show('error');
   }
   private function OnCompleteHandle(E:Event):void{
    LoadedSM=SystemManager(_CtmObjLoader.content);
   } 
   private function OnTestCall(e:Event):void{
    Alert.show('Child Event Call');
   }  
   private function MCtestCall():void{
    if(LoadedSM){
     try{
      LoadedSM.document.TestCall('From Parent Call');//TestCall为加载的文件public函数
     
     }catch(e:Error){
      Alert.show(e.message);
     }
    }else{
     Alert.show('请加载文件');
     return;
    }
   }
   private function testAddChildListener():void{
    if(!_CtmObjLoader){Alert.show('请加载文件');return;}
    try{
     LoadedSM.document.addEventListener("EventGoTOParent",OnTestCall);
     Alert.show('设置成功');
    }catch(e:Error){Alert.show(e.message)}
   }
  ]]>
</mx:Script>
<mx:Button label="加载flex子文件" click="LoadSwf();" x="26" y="10"/>
<mx:Button label="为加载的文件设置Listener" click="testAddChildListener();" x="150" y="10"/>
<mx:Button label="测试加载的文件函数" click="MCtestCall();" x="342" y="10"/>
</mx:Application>
第四步:建立flex swf子文件[flexchild.mxml]
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="750" height="444"
  applicationComplete="initApp()" styleName="Border3" fontSize="12">
<mx:Script>
<![CDATA[
  import mx.controls.Alert;

  private function initApp():void{
 
  }
  public function TestCall(msg:String):void{
   mx.controls.Alert.show(msg);
  }
  private function EventGoToParent():void{
   dispatchEvent(new Event('EventGoTOParent'));
  }
   
]]>
</mx:Script>
<mx:Button x="327" y="148" label="向Parent通知事件" click="EventGoToParent()"/>

</mx:Application>
运行试试，加载flex swf文件完成,下面讲加载flash cs3 swf文件吧
第一步:建立flex主文件1[mainforflash.mxml]加载flash cs3 swf外部文件用
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:ns1="ManageView.*" fontSize="12">
<mx:Script>
  <![CDATA[
   /*
   Flex 控制加载外部的swf文件[子文件为flash cs3 版]
   */
   import mx.controls.Alert;
   import Package.mySwfLoader;
   import flash.utils.setTimeout;
   [Bindable]private var _mySwfLoader:mySwfLoader;
   private var LoadedSM:MovieClip;
   private function LoadSwf():void{
    if(_mySwfLoader){
     _mySwfLoader.LoadThis('flashchild.swf');//flashchild.swf你自己去写了，我不太会，但我做了一个简单的，可用的
    }else{
   
     _mySwfLoader=new mySwfLoader('flashchild.swf');
     _mySwfLoader.addEventListener(IOErrorEvent.IO_ERROR,OnFailHandle);
     _mySwfLoader.addEventListener(Event.COMPLETE,OnCompleteHandle);
     this.addChild(_mySwfLoader);

    }
    _mySwfLoader.setStyle('horizontalCenter',0);
    _mySwfLoader.setStyle('verticalCenter',0);   
   }
   private function OnFailHandle(e:Event):void{
    mx.controls.Alert.show('error');
   }
   private function OnCompleteHandle(E:Event):void{
    if(_mySwfLoader.content)Alert.show('ok0');
    try{
     LoadedSM=_mySwfLoader.movieClip;
    }catch(e:Error){Alert.show(e.message)}
   } 
   private function OnTestCall(e:Event):void{
    Alert.show('Child Event Call');
   }  
   private function gotoAndPlay(frame:int=0):void{
    //(_CtmObjLoader.loader.content as MovieClip).
    if(LoadedSM){
     try{
      LoadedSM.gotoAndPlay(frame);
     
     }catch(e:Error){
      Alert.show(e.message);
     }
    }else{
     Alert.show('请加载文件');
     return;
    }
   }
   private function stop():void{
    if(LoadedSM){
     try{
      LoadedSM.stop();
     
     }catch(e:Error){
      Alert.show(e.message);
     }
    }else{
     Alert.show('请加载文件');
     return;
    }   
   }
   private function play():void{
    if(LoadedSM){
     try{
      LoadedSM.play();
     
     }catch(e:Error){
      Alert.show(e.message);
     }
    }else{
     Alert.show('请加载文件');
     return;
    }   
   }  
   private function testAddChildListener():void{
    if(!_mySwfLoader){Alert.show('请加载文件');return;}
    var d:DisplayObject=_mySwfLoader.content;
    try{
     LoadedSM.addEventListener("EventGoTOParent",OnTestCall);
     Alert.show('设置成功');
    }catch(e:Error){Alert.show(e.message)}
    //_Url=urltxt.text;
   }
  ]]>
</mx:Script>
<mx:Button label="加载flash子文件" click="LoadSwf();" x="26" y="10"/>
<mx:Button label="为加载的文件设置Listener" click="testAddChildListener();" x="160" y="10"/>
<mx:Button label="测试加载的文件函数gotoAndPlay(0)" click="gotoAndPlay(int(frametxt.text));" x="351" y="10"/>
<mx:TextInput id="frametxt" x="623" y="10" width="63"/>
</mx:Application>

第二步:写flash cs3 文件,这个不在行，我写了个简单的测试，通过 的,所以你就自己写吧
可以调用flash cs3 文件的函数,也可以监听他发来的事件

这个东西好像不行啊！         flex swf子文件[flexchild.mxml]  这个东西是做什么的！
